uyluk posteriorunda miksoid liposarkom tanılı 45 yaşında erkek olgunun evreleme
amaçlı [18F]-2-floro-2-deoksi-D-glukoz (FDG) pozitron emisyon tomografisi
(PET)/bilgisayarlı tomografi (BT)  görüntülemesi yapılmıştır. Olgunun sağ uyluk
orta ve distal 1/3 kesimi posteriorunda yaklaşık
105x92 mm boyutlarda, lobüle konturlu, komşu adale yapılarını iten, BT’de septalarla ayrılmış miksoid-kistik ve yağ bileşenleri
içeren, füzyon görüntülerde ise heterojen artmış FDG tutulumu gösteren (SUVmaks: 3.35) yumuşak doku kitlesi saptanmıştır.
Diğer FDG PET/BT kesitlerinde metastaz
tespit edilememiş olup, görüntüleme sonrasında
kitle total olarak çıkarılmıştır. FDG PET/BT yumuşak doku sarkomlarında
grade belirlemede kullanılmakta olup, biyopsinin nereden alınacağının
saptanmasında da önemli rol oynamaktadır. FDG PET/BT, alt ekstremitesinde
miksoid liposarkom kitlesi bulunan olgumuzun evrelemesinde, metastaz
değerlendirmesine katkı sağladığı için yararlı bulunmuştur.

A RARE LOWER EXTREMITY SOFT TISSUE SARCOMA WITH INCREASED FDG UPTAKE ON FDG PET/CT: A CASE OF MYXOID LIPOSARCOMA

Abstract

A 45
years old man with the diagnosis of myxoid liposarcoma in posterior part of his
right thigh underwent [18F]-2-fluoro-2-deoxy-D-glucose (FDG) positron
emission tomography (PET)/computed tomography (CT) for staging purpose. In posterior
of the middle and distal 1/3 parts of the right femur, a soft tissue mass
measuring 105x92 mm with lobulated
contours pushing neighboring muscles was detected which included septated
myxoid-cystic and fat components on CT images and showed heterogeneously increased
FDG uptake (SUVmax: 3.35) on FDG-PET/CT fusion images. No evidence of metastasis could be
detected on other FDG PET/CT images and the tumor was removed
totally after imaging. FDG PET/CT is being used for grading purpose in soft
tissue sarcomas and plays important role in determining the site for biopsy. FDG
PET/CT was found to be useful in staging of our case with myxoid liposarcoma
because of its contribution to metastasis evaluation.
